Abstract

The invention provides a preparation method of a Grateloupia filicina polysaccharide preservative for red bayberries. The preparation method comprises the following steps: taking and mixing Grateloupia filicina polysaccharides, chitosan, nisin and a film forming assistant, adding the water and an active polypeptide, sending above substances into a thermostatic water bath to prepare a mixed solution, and carrying out emulsification and ultrasonic treatment to prepare the Grateloupia filicina polysaccharide preservative for red bayberries. The preparation method has the advantages of simplicity,easiness in operation, and high preparation efficiency, and the prepared preservative has the advantages of stable properties, good film forming property, excellent preservation effect, long preservation time and good market prospect.

Description

technical field [0001] The invention belongs to the technical field of preservative processing, and in particular relates to a method for preparing a centipede polysaccharide preservative for red bayberry. Background technique [0002] Centipede algae is an important economic seaweed, which is rich in protein, carbohydrates, vitamins, minerals and other nutrients, among which polysaccharides are the main ones. Studies have found that centipede polysaccharides have various biological activities, such as anti-angiogenesis, anti-virus, anti-tumor, anti-coagulation, anti-thrombosis, anti-fatigue and anti-oxidation, etc. Centipede algae is also involved in medicinal aspects, as mentioned in "Chinese Medicinal Spore Plants": "Cure enteritis, wind-heat laryngitis, ascariasis". It can be seen that centipede polysaccharides are not only consumed as food, but also play an important role in agriculture, medicine and industry, and have broad development prospects. [0003] In order to...
